Application of The Hydraulic Shock Absorber to a Vehicle Crash Protection System 710537

Energy absorbing crash protection systems are now being developed using various types of shock absorbing devices. This paper deals with design parameters involved in producing such a system. Basic shock absorber concepts as applied to this problem are treated in general discussion centering on hydraulic devices. Governing equations are presented dealing with the design of a hybrid device combining a shock absorber and a compressible medium return mechanism capable of being used as a 5 mph zero damage bumper system for a passenger car.
